It should here be noted, however, that preferably the hook device 25 atthe lower end of each of the main dents I'I is on 'the opposite side ofthe dent from the hook structure 2| which is provided in the upperportion of each of th main dents I1.

There is also provided means for preventing the warp ends which are notengaged by the hooks in the upper portion of the structure from becomingfouled with the offset portions 22 which are provided to maintain the.spacing of the dents at their upper ends. For this purpose there may beprovided a cap member 26 4made of sheet metal mounted on the upperportion of the frame extending downwardly on both faces, the platelportion 21 on one face thereof vextending to a point below the .offset'portions 22 of the .dent Il.

During the initial entering of `-the warp in the leasing comb, the capmember will, of course, be removed therefrom to permit the "warp ends tobe freely placed in their :respective dent spaces.

In Figs. 3 and 4 of the ydra-wingsthere isv illustrated a modified formof leasing comb I4 in which the bent-over tongue portions :I9 andinserted metallic blocks `2l) and 24 are y'dispensed with, and :in lieuthereof eachV of the dents Il is provided with struck-up hook members2In and 25a, `the hook members 2l*EL :being provided in the upperportion ofthe frame vand the .hook

In 'the yform of leasing comb Ma illustrated in Figs. 3 and 4 there isalso shown a different means of spacing the upper ends =of thedents,each of said dents being provided near its upper end with offsets 22aand 22b preferably Atwo or more in number `in each dent, as theprovision of a .plurality of such offsets in veach `dent will -serve toprevent distortion ofthe individual dents. Furthermore, the-offsets ofleach dent are staggered with relation tothe offsets of adjacent dents-so that said offsets will in each instance :bear against a portion ofthe adjacent dent which lies .fin 4the main plane thereof `and which fisresilient to Va sufficient extent to permit the warpends to pass intothe dent spaces during vthe initial entering thereof.

The form of leasing comb shown in Figs. 3 and 4 is also .provided with'a cap member 26 ias in the other form.

In Figs. 5 to 8, inclusive, 'there Vis shown the manner of manipulation-.of the warp with respect to the leasing comb '(of' either form)hereinbefore described. The warp,..after `leaving the Slasher, passesover a guide rod or roller G', extends through the leasing comb I4 bymeans of which the 'lease is for-med, and then passes over another guiderod or rollerSG2. The usual series of separator rods s1, s2, s3 and s4,are also provided, there being one of these .for vthe warp coming fromeach section Ibeam -on which the warp is primarily wound 'from thecreel, the warp from each section beam spassinglover its respectiveseparator rod. The separator rods are supported in suitable racksorstandards `(not shown) between the guide rod G' and 'the 4leasing combI4. These racks or standards `are arranged in such a manner so that eachseparator rod occupies two different positions inthe formation of thelease, these rods being moved successively from one position to theother as hereinafter more fully set forth.

The leasing comb I4 is so mounted that the same may be shifted sidewisewith respect to the warp as is customary in the use of the common formof hook reed used for leasing, and if desired mechanism (not shown) ofthe same type as is used for shifting the common form of hook reed maybe used for this purpose, or the same may be shifted by hand.

However, in carrying out the method of the Ypresent invention theleasing comb I 4 is also shifted to upper and lower positionsrespectively at different stages in the formation of the lease.

The rst step in the formation of the lease is shown in Fig. 5 of thedrawings. In this instance, the comb or reed is in its lower positionand the separator rods s1, s2, s3 and s4 are in their rearmostpositions, that is, adjacent the guide -rod or roller G. It will benoted that in this position the wa-rp from -all the section beamsextends through the dent spaces of the leasing comb between theV hooks2I in the upper portion of the comb and the hooks 25 in the lowerportion 'of the comb. The comb is now moved' sidewise with `respect tothe warp, whereupon the separator rod s1 is moved from its rearwardposition as shown in Fig. 5 to the forward position as shown in Fig. 6.The warp which passes over the separator rod s1 will now be carried upfree of the hooks 2|, whereupon the comb is then shifted sidewise with-respect to the warp but in the opposite direction. Separator rod s2 is`now moved forward from its rearward position, whereupon all of the warpends controlled thereby -will be caught in the respective hooks 2I ofthe comb. The comb is again shifted sidewise lin the original directionand the Aseparator rod s3 is moved from its rearward to its forwardposition carrying with it -the war-p controlled thereby, raising thesame upward free of the hooks 2'I. 'Ihe comb is again shifted sidewisein the opposite direction after which lthe separator rod s4 is movedforward from its rearward position causing the warp controlled therebyto be engaged by the hooks 2 I.

In this manner, the warps controlled by the separator rods s1 and s3will be raised free of ythe Vhooks 2'I of the leasing comb I4 and thewarps lcontrolled by the separator rods s2 and s4 will 'be engagedthereby, separating the same in two sheets as shown at the forward endof Fig. -6 and into the shed Vlike space thus provided, between the twosheets of warp, the leasing cord or rod vL' is inserted.

The leasing comb I4 is now raised to the position shown in Fig. '7 ofthe drawings, causing all of the warp to be free from engagement by thehooks thereof. A reverse actuation of the separator rods is noweffected, step by step, the leasing comb, however, being in the properposition so that when the separator rod .s4 is returned from its forwardto its rearward position, the Vwarp ends controlled thereby will becaught in the respective hcoks25in the lower portion of the comb. Thecomb :is `now shifted sidewise so that when the separator rod s3 isreturned from its forward position to its rearwardpositionl the `warpends .con- `trolled thereby will pass freely in -the dent spaces beyondthe hooks 25 inthe lower portion of the comb. Likewise with the warpscont-rolled bythe separator rods s2 and s1 the leasing comb in eachinstance being shifted sidewise to selectively engage or permit the warpto pass, as may be required to effect the leasing.

When all of the separator rods are returned to their initial positions,the warp will again be separated by the leasing comb into two sheets asshown at the forward end of Fig. 8, and into the shedlike space thusprovided, between the two sheets of warp, the leasing cord or rod L2 isinserted to complete the formation of the lease. The leasing comb iiimay now be lowered to its initial positicn and the warp thereafter fedthrough the same free of engagement by the hooks thereof.

It will be noted that the method employed differs essentially from thatin which a hook reed of the ordinary type is employed, in that thedouble lease is accomplished by the movement of the separator rods fromtheir rearward to their forward positions and back again instead ofrequiring the same to be returned to their initial positions before thesecond part of the lease is taken. In this manner a considerable economyin the operation is obtained.

It will also be understood that in the practice of the method it is notessential that a leasing comb of either of the types shown be employed,as a reed having a permanently closed top may be used if the same beprovided, in connection with each dent thereof, with two hooks suitablyspaced to be operable in the manner hereinbefore set forth. However, theuse of the comb-like device permits the warp to be more expeditiouslyentered in the dent spaces.
